The Rock Titan is a gigantic, bulky creature that seems to be composed entirely of rough, uneven stone. Its body is very large and barrel-shaped. His legs are short and his feet are flat, while his arms are relatively long and end in four-fingered hands.

He has two comparatively small, draconian heads placed side-by-side on the top of his body. Both heads have thick necks, a peculiar lower jaw with four very large, blunt teeth. His eyes are very small and red, and the inside of both mouths are red as well.
